How do insects help farmers?
Insects pollinate 75 percent of the crops used directly for human food worldwide. They contribute $210 billion in agricultural earnings. But honeybees are now so scarce, according to a new study from the University of Reading, that Europe is 13.6 million colonies short of the number needed to pollinate crops there.
Why are insects important to the ecosystem?
Insects pollinate many of our fruits, flowers, and vegetables. Insects are very important as primary or secondary decomposers. Without insects to help break down and dispose of wastes, dead animals and plants would accumulate in our environment and it would be messy indeed.
How does understanding the insect makes you a better person?

Insects go through circadian rhythms of activity and passivity but some do not seem to have a homeostatic sleep need. Insects do not seem to exhibit REM sleep. However, fruit flies appear to sleep, and systematic disturbance of that state leads to cognitive disabilities.

Do insects use oxygen?
Insects get oxygen from the air to fuel muscles and tissues. Those insects that move a lot, particularly through flight, need more oxygen than sedentary insects. Eventually, insects release carbon dioxide as waste back into the air.
Do all insects need oxygen?
Insects, like people, require oxygen to live and produce carbon dioxide as a waste product. That, however, is where the similarity between the insect and human respiratory systems essentially ends. Insects do not have lungs, nor do they transport oxygen through a circulatory system in the manner that humans do.
Do mites need oxygen?
Oxygen requirements. Scabies mites represent an unusual taxon of arthropods and metazoan animals that require oxygen (aerobic) but lack an organized respiratory system for obtaining it.
